United Utilities have confirmed that they're (another) two weeks behind schedule. The window company still want to go ahead with next week though: they'll be bringing the windows two or three per day, in a small van, and we'll be carrying them down the pavement into the house.
The builders are almost done with the plasterboarding and insulating; after they've done that I've told them to get ready for the window fitters next week.
I've chased up the Cavalok cavity closer, hopefully this should be arriving on Friday (the builders are ripping out the old windows and fitting the cavity closers, then the window company put the new one in).
Also, the building society surveyor came today to do a re-valuation. He seemed to be OK with what we'd done so far (despite the fact that we hadn't stuck to the original schedule).
